Some user in our intranet use very stupid password and I need enable their POP3 acces only from their own machine (in intranet). For others (with complicated password) I want enable POP3 acces from any machine in internet. For example: User "franta" (with password "xxx") can access POP3 only from machine with IP "100.100.100.100". User "petr" (with complicated password ...) can access POP3 from any machine. I supposed that I can use pam module "pam_rhosts_auth.so". I tried ADD it in /etc/pam.d/pop3, but it make error (PAM unable to resolve symbol: pam_sm_acct_mgmt). Please, which module can I use for this function? Thank you, Petr SPATKA
